The effect of simultaneous addition of multiwall carbon
nanotubes (MWNTs) and a reactive compatibilizer (styrene
maleic anhydride copolymer, SMA) during melt-mixing
on the phase morphology of 80/20 (wt/wt) PA6/ABS blend
has been investigated. Morphological analysis through
scanning and transmission electron microscopic analysis
revealed finer morphology of the blends in presence of
SMA 1 MWNTs. Fourier transform infrared spectroscopic
analysis indicated the formation of imide bonds during
melt-mixing. Non-isothermal crystallization studies exhibited
the presence of a majority faction of MWNTs in the
PA6 phase of 80/20 (wt/wt) PA6/ABS blend in presence of
SMA 1 MWNTs. Rheological analysis, dynamic mechanical
thermal analysis, and thermogravimetric analysis have
demonstrated the compatibilization action of simultaneous
addition of a reactive compatibilizer (SMA copolymer) and
MWNTs in PA6/ABS blends. An attempt has been made to
investigate the role of simultaneous addition of SMA
copolymer and MWNTs on the morphology of 80/20 (wt/wt)
PA6/ABS blend through various characterization techniques.
